Could this be making me feel odd?

I've just come back from my holiday on Friday, and I didn't eat much at all. I get homesick really easily, and with me being away, I just didn't want to eat. I had a full meal on the Thursday evening (scampi and chips, at about 5.30pm) and then didn't eat anything again until lunchtime on the Friday (sausage roll). I've had a bit more food today, followed by a chinese with my boyfriend for tea. Now I just don't feel right, I have a lot of trapped wind, I feel bloated, and just generally icky. Is this normal? When will I start to feel better?
